A Mathematical Clarification of Deep Discovering out

Deep learning has been drastically changing the field of machine learning (and the world accordingly) as machine learning has been much more widely applied now to different application scenarios – such as recommender systems, speech recognition, autonomous driving, and automatic game-playing. In 2018, Professor Joshua Bengio, Geoffrey Hinton, and Yann Lecun received the Turing award…

Holding Users In opposition to Substandard-Web site Question Forgery

Imagine this scenario: after logging into your bank account and checking your balance, you navigate to another website. Suddenly, you notice your account was hijacked! Funds are being transferred and the attacker tries to reset your password. You are security-conscious and never fall for phishing scams or share your password, so how could this have…

Constructing Microservices Pushed by Performance

At Roblox, we’ve adopted the microservices paradigm and built a container-based development platform. Our International Growth team pioneered this effort by implementing services that embraced the new approach and introduced new practices aiming for high concurrency and scalability. Now we look to how we can improve our overall performance metrics, and we’ve delivered consistent results…

Improving Server Handy resource Usage by Tracking Memory Leaks

About a year ago we noticed early indications of a pattern emerging showing a decreased capacity in our game servers. At the onset there was little to no player impact because we had plenty of headroom but our buffer was quickly dwindling. A game server will happily accept new players or start new games as…

Constructing a Pleasurable and Civil Neighborhood

Dear Roblox Community – Roblox was designed for kids and teens, and we have a responsibility to make sure our players can learn, create, and play safely. This continues to be our most important priority and that will never change. Safety is not a retrofit; it’s been in our DNA since day one. We have…

Be taught the contrivance to Device a Luau: Augmenting Lua’s Syntax With Kinds

For a very long time, Lua 5.1 was the language of choice for Roblox. As we grew, so too did the demand for better tooling support as well as a more performant VM. To answer this, we started the initiative to rebuild our Lua stack named “Luau” (pronounced /lu-wow/), with the goal of encompassing the…

Bettering Simulation and Performance with an Developed Physics Solver

In mid-2015, Roblox unveiled a major upgrade to its physics engine: the Projected Gauss-Seidel (PGS) physics solver. For the first year, the new solver was optional and provided improved fidelity and greater performance compared to the previously used spring solver. In 2016, we added support for a diverse set of new physics constraints, incentivizing developers…

Roblox Physics: Constructing a Higher Sleep System

Let’s talk about “sleep” in a physics engine. The purpose of a sleep system is to stop doing work on bodies that aren’t moving, and start doing work when they will be. The challenge is picking the best heuristic for transitioning between these states. A common approach in other engines is to monitor a body’s…
